MACHINE FOR ATTAGI-IING BEADS T FABRICS.

Application filed July 10, 1922. Serial No. 573,850.

To all whom it may concern:

Be 1t known that I, RAPHAEL BoLANoI, a

citizen of Costa Rica, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented new and useful Improvements in Machines for Attaching Beads to Fabrics, of which the following is a full, clear, and exact description.

This invention relates to attachments for sewing machines or embroidering machines for adapting them for attaching beads to fabrics.

In the manufacture of goods decorated by the use of beads or stringed heads a great amount of labor in attaching the beads to the goods is performed by hand; The process of attaching beads to fabrics by hand is very tedious and slow thus making beaded goodsv expensive. Further,-unless the workers are skilled in the art of decorating goods by the use of beads the work is apt to be irregular and accordingly presents a poor appearance.

The general object of this invention is the provision of a simple and efiicient attachment for mounting on sewing machines or embroidering machines for adapting them for use in sewingstringed beads to fabrics.

A further object of the invention is the provision of attachments for mounting on sewing machines or embroidering machines whereby the machines may be adapted for following any pattern. 7

These ob'ects are accomplished by rotatably mounting on the sewing machine or embroidering machine means for carrying the stringed beads and means for feeding the beads, and associating with the carrying and feeding means means for rotating them to wind the bead string about the sewing thread, said revolving means having provided in conjunction therewith means for retarding or advancing the motion of the carrying and feeding means as they revolve.

These and other objects of the invention will be more easily understood from the following detailed description and accompanying drawings, in which- Figure 1 is a side elevation of an embroidering machine, showing the attachment for converting it into a machine for attaching beads to fabrics;

Figure 2 is a bottom plan view of the embroidering' machine;

Figure 3 is an end elevation of the embroidering machine Figure 4 is a vertical longitudinal section through the embroidering machine, showing the bead feeding means in section;

Figure 5 is a section along the line 5-5 Figure 4;

Figure 6 is a section along the line 6-6, Figure 4;

Figure 7 is a section along the line 7-7, Figure 6;

Figure 8 isa section along the line 8-8 Figure 8.

Referring to the above-mentioned drawings in Figure 4, an embroidering machine 15 is shown provided with a needle bar 10, a needle bar sleeve 11, and a feed rack 12. The needle bar 10 carrying the needle 33 is operated by means of a shaft 13 and cams 14. The needle bar sleeve 11 referred to above is supported in the embroidering machine 15, and the needle bar which carries the needle is so mounted in the needle bar sleeve 11 as to slide freely.

A gear 16 is fixed to the needle bar sleeve 11 while a gear 17 integral with a sleeve 18, is rotatably mounted thereon. The sleeve 18 seats on the upper face of the fixed gear 16 so that it does not move vertically along the needle bar sleeve. A plate 19 having an arm 20 attached thereto is attached to the sleeve 18. Rotatably mounted on the arm 20 is a spool 22 for carrying the stringed beads 21.

An arm 24 has a lug 26 extending at right angles thereto. This lug 26 has a longitudinal slot 27 through which a set screw 25 may be projected. The set screw 25 engages in a threaded opening provided in the sleeve 18 and thereby the arm 24 may be adjustably attached to the sleeve 18. A feeding device 23 is carried by the arm 24. This feeding device consists of a two-piece casing, one section 28 being formed integral with the arm 24, the other section 29 being adjustably supported on the section 28 by means of guides 30 which are slidably mounted in grooves 31 formed in the section 28. The two sections of the casing are held in any desired relative positions to one another by a screw 32. A worm 84 integral with a shaft 35 is rotatably mounted in an arm 37 integral with the section 28 of the casing, and a plate 38 attachedto the arm 24 by means of a screw 39. Mounted on the shaft 35 is a bevel gear 36, retained in position by means of sleeves 41 and 42. These sleeves also serve to retain the shaft 35 in This screw 32 is mounted in a threaded openposition since the sleeve 41 seats on the arm 37 and the sleeve 42 bears against the plate 38. It will be seen from this construction that on removal of the plate 38, the shaft 35 and worm 34 may be removed from the easing. The section 28 has a notch 44 cut in its lower end for allowing the stringed beads 21 to pass therethrough and for steadying the lower end of the worm 34 which fits into the notch. The worm 34 may be of any de sired size, depending on the size of the beads 45 carried by the string 40. The section 29 of the two-piece casing 23 may be adjusted by means of the screw 32 so that the casing may accommodate any size of worm 34.

ing provided in the section 28 and engages in a threaded opening formed in an L-shaped member 84 slidably mounted on the casing section 28. Projections 85 formed on the casing section 29 abut against this L-shaped member 84, the latter limiting the movement of the casing section 29 to the right as shown in Figure 6. A spring 83 mounted in an opening 82 of the section 28 of the feeding device is engaged by the pin 81 attached to the section 29 and movable in a slot in section 28, and when a large bead passes down the trough 43 and is forced downward by the worm 34 the section 29 of the casing of the feeding device moves outward, compressing the spring 82. Thi movement is, of course, very slight and there is suflicient play between the screw 32 and its connected parts to permit such movement. Normally the spring 82 retains the sect-ion 29 in the position to which it has been adjusted by means of the screw 32. A curved trough is formed integral with the section 29 to serve as a means for feeding the stringed beads 21 from the spool 22 into the casing. The bevelgear 36 carried by the shaft 35 meshes with the fixed gear 16 mounted on the needle bar sleeve 11.

Motion is transmitted from the main shaft 13 to the gear 17 through a differential and a plurality of sleeves, gears and shafts. The differential consists of a gear 46 loosely mounted on the shaft 13 and retained in position by means of a hub 47 and the bevel gear 48 which is pinned to the shaft 13. Another bevel gear 53 is loosely mounted on the shaft and connected to sleeve 54. Motion is conveyed from the bevel gear 48 to the bevel gear 53 by means of two bevel gears 51 and 52 carried by arms 49 and50, respectively. The sleeve 54 which is loosely mounted on the shaft 13 is connected to a gear 55 by a tongue 56. This gear 55 is held against endwise movement by a collar 57. Extending parallel to the shaft 13 is a shaft 58 which is rotatably mounted in bearings carried by the embroidering machine. Loosely mounted on this shaft 58 is a sleeve 59 to which a gear 60and a bevel gear 61 are pinned. The gear 60 meshes with the gear 55. The bevel gear 61 meshes with a bevel gear 62 mounted on the upper end of a vertical shaft 63 carried by the sewing machine frame. On the other end of the shaft 63 a gear 64 is mounted which meshes with an idler 65 and through the idler operates a gear 66 rotatably mounted on the frame 15. Thus the motion of the shaft 13 is conveyed through the bevel gears 48, 51, 52 and 53, sleeve 54, gears 55 and 60, sleeve 59, bevel gears 61 and. 62,- shaft 63,

gears 64, 65 and 66 to the gear 17. Themotion of the gear 17 may be advanced or retardedby means of the differential gearing. This differential gearing is operated through a system of gears and shafts. crank 67 is mounted'on a verticalshaft 68,

to the end of which a bevel gear 69 is fixed.

This bevel gear 69 meshes with a bevel gear 70 fixed to one end of a horizontal shaft 71,

to the other end of which a bevel gear 72 is fixed. Motion is transmitted from' the bevel gear 72 to the bevel gear 76 pinned to the shaft 58' through a shaft 7 3,- on the ends of whichbevel gears 74 and 75 are mounted, the bevel gear 74 meshing with the bevel gear 72 while the bevel gear 7 5 meshes with the bevel gear 76. By the operation of the bevel gear 76 through the gears and shaft set forth above the gear'77, which controls the operation of the gear 46,. may be operated through the shaft 58. It will be seen that by the operation of the gear 46 the bevel gears 51 and 52 may be rotated about the shaft 13 thus advancing or retarding the motion of the sleeve 54 about the shaft 13.

The needle bar 10 is operated'by the shaft 13 through the cams 14 and the gearing system supplied in any of thewell known machines, such as shown inPatent 110.228,- 445, June 8, 1880. In the preferred construction of this machine, the gear system for operating the gear 17 would be so designed that the gear 17 Would rotate once about the needle bar sleeve 11 for each stroke of the needle bar 10. However, this might be altered so that the gear 17' and sleeve 18 would only rotate once for every two or more strokes of the needle bar.

As shown in Figure 1, the sewing thread 78 is mounted below the cloth'boa-rd 79 so that it will not become entangled with the bead spool 22 as it revolves about the needle bar sleeve 11. This means of mounting the sewing thread or embroidery thread- 78 below the cloth board is well known and is no part of the invention but is set forth in order to' more clearly explain the 'cons'truction'of the machine.

The operation of the attachments de scribed in detail above is as follows:

When the machine is set in motion, the gear 17 as described above rotates once about the needle bar sleeve 11 for every stroke of the needle bar 10 and needle 33. As the gear 17 rotates about the needle bar sleeve, the sleeve 18, carrying the spool 22 and the casing 23, also rotates about the needle bar sleeve. The gear 36 meshing with the fixed gear 16 is rotated and in turn rotates the worm 34, serving to feed beads 45 carried by the bead string 40 downward through the notch 44 in the section 28 of the casing. The worm may be designed to feed one or more beads for each revolution of the gear 17 and the casing 23 about the needle bar sleeve 11. As the spool 22 and casing 23 are revolved about the needle bar sleeve 11, the bead string 40 is drawn underneath the needle 33 and therefore wound about the sewing thread 78. Thus the bead string 40 is attached to any fabric which is being sewed by the use of the thread 7 8.

Designs stamped on a fabric are usually made by the use of curved lines, and in order to follow these curved lines it becomes necessary to either retard or advance the time at which the bead string is drawn underneath the needle 33 in order to follow the lines of the designs. This will be readily understood if we imagine the fabric 80 being drawn to the right as seen in Figure 4. In this case it may be necessary for the casing 23 to be rotating once for every stroke of the needle 33. If now the line of the design extends to the front it will become necessary, in order to have the beads 45 attached in the proper place, to advance the motion of the casing 23 about the needle bar sleeve 11 in order that the bead string 40 will be drawn beneath the needle 33 about 90 in advance of the point at which .it was drawn under when the fabric was moving to the right. This is accomplished by rotating the crank 67 clockwise which causes the arms 49 and 50 to rotate clockwise about the shaft 13 when viewed from the right in Figure 4. In order to retard the motion of the casing 23 about the needle bar 11 the crank would be rotated counterclockwise. This would be necessary in order to follow a design line running to the rear as viewed in Figure 4.

The feed rack 12, as shown in Figures 1, 3 and 4, is provided for feeding a fabric past &

the stitching mechanism and is operated by any well known mechanism used in embroidering machines. This rack, which is circular, serves to hold the fabric 80 taut while the beads are being attached thereto.

In order to vary the speed of the worm 34 it would be necessary to change the gears 16 and 36. If it is desired to change the size of the beads 45, the worm 34 may be removed and a larger worm introduced in order to feed the beads. The casing 23 has been made adjustable so that it can be changed in order to receive any size of worm.

I would state in conclusion. that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated since manifestly the same can be considerably varied without departing from the spirit of the invention as defined in the appended claims.
